PA 3000
Triple channel ICP® signal conditioner
DESCRIPTION
PA 3000 is a triple channel, portable conditioner for ICP® signal with
built-in battery pack. Each channel has an independent control of
gain level and frequency response. Settings can be adjusted by buttons on the front panel. The module has built in sensor circuit diagnostics and detects short and open circuits in the measurement
chain. The device status is indicated by LEDs on the front panel,
which show as follows:

PA 3000 features innovative ICP® input conditioning circuit, which
has a very short response time of the impulse excitations (e.g. force
signal from sensor built in a modal hammer used for modal analysis)
and high output signal stability in time (lack of voltage signal
fluctuation at zero excitation, which is typical for standard ICP®
signal conditioners). Configurable gain level (0dB, 20dB, 40dB)
allows the module to be used with sensors having various sensitivity,
as well as perform measurements in a wide range of excitation
range.
The low pass and high pass filters (typically 10Hz and 1kHz) allow
machine vibration measurements according to diagnostic norms. The
high grade aluminum housing and the keypad made from durable foil
make the device very suitable for work in harsh industrial
environment. The battery power supply allow the measurements
without access to the electrical socket.
